.STEAM-CYLINDER LUBRICATOR.

, SPECIFICATION forming part of Letters Patent No. 291,068, dated February 26, 188i,

Application filed April 13, 11:81. (No model.)

To all whom it nmy concern:

Be it known that I, WAsHINqToN LEROY PARKER, of Chicago, Illinois, have invented a new and useful Improvement in Steam-Cyl- 'inder Lubricators, which has never before been known or used in this or any other coun: try, and of which the following is a sufficient description.

My invention relates to the class known as visible-feed lubricators, in which the lubri cant is seen to pass drop by drop through a transparent tube or chamber; and the immediate objects of my invention are to provide a lubricator which may have the condensing and oil chambers combined in one continuous cylinder or cup; which shall have but one connection with the parts to be lubricated which shall have the connection or oil-feeding pipe issuing directly from. the base in such a manner that the lubricator may be attached directly to the steam-cylinder at the point at which the lubricators in common use are usually attached; which shall feed the lubricant by carrying it drop by drop by and along with a positive current of water of condensation through a transparent tube or chamber, and thence into the parts to be lubricated. These objects I attain by a mechanism which is believed to be sufficiently set forth in the following description, reference being first had to the accompanying drawing,which is a section taken through such lubricator at its center.

A is a condensing-chamber separated from the oil-chamber B by the diaphragm L.

G is a pipe issuing from a point in or near the base and attaching the lubricator to the parts to be lubricated.

F is a tube within the cylinder of the lubricator, connected with and leading from the pipe G through the oil-chamber B, thence through diaphragm L, thence through to the top of the condensing-chamber A, into which it opens at f, and'also connecting with the plug 0 and avoiding the entrances of the tubes 6 and e.

Eis a plug screwed or otherwise attached to the side of the lubricator-cylinder in the line of intersection of the diaphragm L in such a manner that its tubes 6 and 6 will open, respectively, into the condensing-chamber A and oil-chamber B, thus connecting the two chambers. The tubes (2 and 0 may be so ar- G is aplug attached to the side of the cylinder above the plug E, but below the upper extremity of the pipe F, and which connects the tube D with the pipe F at the point a.

H is a drain-cock for chamber B.

I is an oil-cup for filling.

J is a plug opening into chamber A. The chambers A and B may be made continuous, or they may be screwed together, if desired. The tube or pipe F may be cast with the cylinder, or it may be a separate tube proceeding from the pipe G to the top of the chamber A, as described, and having a branch tube to make its oonnectionwith the plug C, in which case the tube F and its branch may be of any desirable size and proportion and relation.

The use and value of my invention will be shown by the following: The lubricator being first attached to the parts to be lubricated by the pipe G, the oil-chamber B filled with oil, and the condensing-chamber with water, the cooks opened, the water will pass from the condensing-chamber A through the tube 6 into the transparent tube D. The valve M being then opened, the connection with parts to be lubricated being also opened, the water will pass slowly from the tube D through the tube 6 into the oil-chamber B, and the oil so dis placed will pass up through the same tube 0 into the tube D. The water of condensation being formed much faster than thus used, by feeding it into the oilchamber B will create and maintain a constant and very considerable current or flow of water from the base of the condensing-chamber A through tubes 6 and D, and thence into E. The oil displaced as described into the tube D will be carried by this current into the parts to be lubricated.

Heretofore many visible-feed lubricators have been devised in which the lubricant is seen to pass drop by drop through a transparent chamber; and lubricators have also been devised that carry the lubricant by a current of condensed steam.

The novelty of my invention may be seen in this, that the oil and condensing chambers may be made in one continuous piece; that the lubricator may be attached by a pipe issuing from the base to the steam-cylinder at the point at which such lubricators as are now commonly employed are attached; that the transparent tube or chamber through which the lubricant passes may be disposed at any desirable angle, since the lubricant is carried through it by a current, and thus the whole may be made more compact; that a continuous current of water through the feed-connections keeps the transparent tube and all other parts of the feedconnections free from any deposits, or from clogging oil, likely to retard the action; that the lubricant is carried by a positive feeding current of water of condensation throughatransparcnt tube or chamber, and thence to the parts to be lubricated.

Having thus shown the construction, utility, and novelty of my device, what I claim as my invention, and desire to secure by Letters Patcut, is

1. In a visiblefeed lubrieator, the plug E, having the tubes 6 and 6, so arranged as to form awater-trap, as and for the purpose set forth.

2. In a visible-feed lubrieator, the plug E, having the tubes 6 and 0, so arranged that when it is attached to the cylinder at the line of intersection of the diaphragm a connection of the chambers A and 13 will be effected, as and for the purpose set forth.

3. In a visible-feed lubrieator, the combination of the plug E, having the tubes 0 and 6, arranged as described, and the valve M, with the transparent tube or chamber D, plug 0, and the pipe F, as and for the purpose set forth.

4. In a visiblefeed lubrieator, the pipe G, connected with the feed-pipe F, and issuing from the base of the cylinder and attaching directly to the parts to be lubricated, as described above, as and for the purpose set forth.

5. In avisible-feed lubrieator, the combination of condensing-chamber A and oil-chamber B, connected by a single passage through the plug E by the tubese and c, with the plug E and transparent tube or chamber D, as and for the purpose set forth.

6. In a visible-feed lubrieator, the combination of chambers A and B, separated by diaphragm L, with plug E, having tubes 6 and 6, arranged as described, and valve M, with transparent tube D, plug 0, pipes F and G, as and for the purpose decribed.

7. The method of feeding oil in a lubrieator, which consists in carrying it drop by drop from the oil-chamber in and by a current of moving water to the parts to be lubricated.

8. In avisible-feed lubrieator, the transparent tube or chamber D, connected at its base bya double connection with the base of the condensing-chamber and the top of the oilreservoir, as described.

9. The combination of the transparent tube or chamber D withv the condensingehamber A, being connected therewith, as described, and for the purpose set forth.-

10. In a lubrieator, the method of feeding oil to the parts to be lubricated, which consists in discharging it in drops from the oilchamber by means of hydrostatic pressure and then carrying it by and in a current of water to the parts to be lubricated.

11. In a lubrieator, the method of feeding oil to the parts to be lubricated, which consists in discharging it in drops from the oilchamber by means of hydrostatic pressure and then carrying it to the parts to be lubricated by means of its inferior specific gravity and the action of a moving current of water.
